Sorry, I misunderstood you. I believe that Makergear recommends starting at 1487 using a 16x micro stepping controller, which is usually how the RAMPS are set up. Since the plastruder has high reduction you may want to change that to 8x and adjust the settings in your firmware. It unfortunately depends a lot on your filament and the tension in the idler, so you will definitely have to adjust it to get it right.
I recommend the Ultimachine PLA; not brittle, good dimensional stability along the length (Chinese PLA often is put on the spool warm resulting in stretched or not round filament), prices are okay, and they always throw in samples of other colors.
